This invention relates to improvements in 6 nozzle-of a bidet in an inoperative position adjacent the rim of a bowl and to manually adjust said nozzle to an operative position substantially in the center of said bowl where a spray from the nozzle will be directed up- !0 wardly. a

An object ofthe present invention is to provide an improved bidet, the movement of the nozzle of which from an inoperative or normal to an operative position is controlled by the flow of the liquid which issupplie d to said nozzle.

Another object is to control the movements ofrthe nozzle to operative and inoperative positions, respectively, by the-pressure created by the flow of liquid to said nozzle and 'the cessation of said flow.

A further object is to utilize the pressure of the liquid supply for the nozzleto move the same to both its operative and inoperiative positions;

The above and other objects will appear more clearly from the following detailed de- 'scription, when taken in connection withthe accompanying drawings, which illustrate preferred embodiments of the inventive idea.

In the drawings I V a Figure 1 is a top plan view, partly broken away and shown in section, of a toilet bowl;

Figure 4 is a section on the line H of Figure-3; V a V Figure 5 is a section on the line 55 of Figure 3;

Figure 6 is a fragmentary section similar to Figure 2, showing a slightly different form of the invention and its application to the the bidet shown in Figure 6; and

Figure 8 is a similar view of still'another form of the invention.

In accordance with the present invention, as exemplifiedin 'Figuresl to 5, the body 10 of the bidet is'mounted in 'the side and ad jacent the riniof the bowl-l1 which may be of standard construction. To mount the body in position, a-sleeve12 is threaded into one no end thereofandextended through anopen-V ing 13 in the bowl. A cap or nut 14 is engaged with the inner end of said sleeve and suitable gaskets 14: are interposed between the bowl and said body and cap toprevent "e5 leakage. A nipple 15 is mounted for turning Figure 7 is a longitudinalse'ction through movement in the sleeve 12 and is provided with ducts 16 for the passage of liquid from the body 10 to the nozzle17 which iscarried by said nipple. A coupling 18 is used to con- 0 nect thenipple and nozzle and is adjustably secured to the former by a set screw-v19. Thus,

the nozzle is turnable with the nipple to opera'tive or normal and inoperative positions,

asindicated in dotted and full lines, respectively, in said figures. In order-that the nozzle will be completely disposed to oneside of the bowl'and beneath the rim thereof when in it's inoperative position,;thesa1ne-is made of arcuate form so as to conform generally ito the contour ofthe bowl and extend in a horizontal direction thereabout. The head 20 of the nozzle projects laterally so that when the nozzle is turned to its operative position the flow of liquid therefrom will be directed upwardly from a point approximately at the centerof the bowl. "At the end of the body10remote'from the bowl, the same is provided with a lateral in-,

let 21 to which is joined the ,feed pipe 22 connecting said body with a valve-23-to which liquid is supplied from the hot and cold Water pipes 24. The valve 23 maybe of a con --ventional construction capable of controlling the-admissi on of hot or cold water, or a mix- 5 ture of both, to said pipe 22, and of completely shutting off this supply.

The pressure of the liquid created by the flow entering the'body 10 when said valve 23 is opened, and the cessation of-said flow with 1611 a consequent reduction of pressure, when said valve is closed, are utilized to control, respectively, the movements of the nozzle 17 to its operative and inoperative positions. To this end, a piston 25 is mounted for longitudinal and rotatable coordinate movements within the body 10 and these movements are translated into a turning movement of the nipple 15 and consequently of the nozzle 17. Said coordinate movements are effected by engaging theinner end of a guide pin 26 in a groove 27 formed in the piston. The inner portion 28 of said grooveis of spiral form so that as the piston is moved in either direction in the body 10 it isalso caused to rotate. The amount of this rotation determines the limits of the turning movements of the nozzle 17 from its inoperative to the operative position and vice versa. The remaining portion 29 of'the groove27 extends longitudinally of the piston so that when the pin 26 is engaged in said portion the piston will only move longitudinally and will therefore have no effect upon the nozzle 17 The translation of the coordinate movements of the piston into .the turning movement of the nozzle is accomplished by providing the inner end of the piston with a socket 30 which receives the stem 31 of the nipple 15.

In practice, with the parts in the position shown in Figure 3, the admission of a flow of liquid into the outer end of the body 10 by opening'the valve 23 Will create a pressure upon the piston 25 suflic'ient to move the same inwardly against the tension of a retractile spring 32 connecting said piston With the cap 33. During the initial inward movement of the piston the same is also rotated by the pin 26 engaging in the portion 28 of the groove 27. These coordinate movements of thepiston cause the stem 31' to enter its socket and at the same time be turned with the result that the nozzle is swung from its normal position to the operative position shown in dotted lines. When the nozzle has reached the latter position, the pin 26 enters the portion 29 and the remainder of the movement of the piston is only longitudinal. Im.

mediately following the beginning, of the latter movement, the outer end of the piston passes and uncovers the entrances to the bypass ducts 34 formed in the body 10, thereby permitting the liquid to flow around the piston, through the ducts 16 in the nipple 15, and into the nozzle 17; This, flow continues as long as the valve 23 remains open, but upon 7 cessation of said flow the pressure against the piston 25 is reduced and the spring 32, whlch is now expanded, acts to move the piston toward its original position. The initial movement of said piston is only longitudinal and during the same a portion of the column of liquid in front of itis discharged through the ducts 34. Whe'nthe pin 26 reaches and enters the portion 28 of the groove 27 are said piston when pressure .of the bowl 11 and beneath the chamber 36 thereof, and the feed pipe 37, which is the equivalent of the pipe 22 and which is connected to a valve (not shown)v similar to the *valve 23, enters the end of the body 10 in direct alignment with the piston 25. The pin 26 and groove 27 are provided to effect the turning of the nipple 15 and'nozzle 17', and'the ducts 34 by-pass the liquid around the piston as previously described in the. first embodiment. 'Due to the connection of the pipe 37 directly with the end of the body 10, the spring 32 is interposed between the inner end of the piston and an abutment 38 so as to be compressed by the inward movement of the former and thereafter expand to restore thereagainst is relieved. v

The form of the bidet illustrated in Figure 8 isso constructed as to utilize the pressure created by the flow of liquid to move the nozzle from its inoperative or normal position to the operative position thereof and also to restore said nozzle to its normal position after use. To this end, the body 39, which is adapted to be attached to the bowl 1n a manner similar to thebody 10, has mounted therein for longitudinal sliding movement the nozzle 40 shownin its retracted or inoperative position in said figure. Apiston: 41

carries one or more spring-pressed valves 42 which normally remainrc'losed and prevent the passage of liquid from the inlet 43into the nozzle. A valve 44 is connected to the inlet 43 and also to a second inlet 45and may be of any conventional construction which will enable the shutting off of the supply of liquid from the pipe 46, or the admission of said liquid into either of the inlets 43 or 45. Upon admission of liquid through the inlet 43 the. pressure thereof will act against the 1 piston 41 and move the same inwardly to project the nozzle 40 to its operative position.

The valves 42 remain closed during this movement until the nozzle has reached its operative position, whereupon the inner ends of said valves will be opened by contact with the adjacent endof the body 39, thereby permitting the liquid entering the inlet 43 to pass through the piston and into the nozzle.

During the movement of the nozzle to its,

eration of the device'in which said liquidwas operative position the liquid'which has aceumulated in the body, due to a previous op-.

admitted through the inlet 45, is forced through the relief duct 46 at the inner end of said body. To restore the nozzle to its inoperative position the valve 44 is operated to disconnect the flow from the inlet 43 and transfer the same to the inlet 45 Pressure is now exerted upon the opposite side of the piston 41 which then moves outwardly to withdraw the nozzle toward its normal position and this movement continues until the piston contacts the adjustable stop pin 47 at the outer end of the body 39. During said movement the liquid in the body between the inlet 43 and the piston is discharged through the relief duct 48 extending longitudinally of the body from a point adjacent said inlet 43 to the inner end of said body.
